A Dartmouth College professor plans to donate half of the proceeds from his latest book to Antifa, the radical protest group labeled as “domestic terrorists” by the federal government.

Mark Bray, a lecturer at the elite college, gained popularity after publishing Antifa: The Anti-Fascist Handbook, in which he openly admits that the group rejects the classical understanding of free speech.

“At the heart of the anti-fascist outlook is a rejection of the classical liberal phrase incorrectly ascribed to Voltaire that ‘I disapprove of what you have to say, but I will defend to the death your right to say it,’” the professor writes, noting that “after Auschwitz and Treblinka, anti-fascists committed themselves to fighting to the death the ability of organized Nazis to say anything.”

While it is unclear how personally involved Bray is in the organization, a recent profile of the controversial professor in The Chronicle of Higher Education briefly notes that he plans to donate half of the proceeds from his book to an unnamed fund that helps support the legal, medical, and personal expenses of Antifa activists.

Notably, POLITICO reported in September that internal documents had revealed that both the Department of Homeland Security and the FBI had referred to Antifa as “domestic terrorists.”

In an August statement, issued shortly after Bray had started to participate in interviews with the national media, Dartmouth’s President’s Office condemned Bray’s views and sought to distance

“Recent statements made by Lecturer in History Mark Bray supporting violent protest do not represent the views of Dartmouth,” the statement read, adding that while the university “embraces free speech,” the “endorsement of violence in any form is contrary to Dartmouth values.”

A group of 17 faculty members subsequently undermined those assertions, however, sending a letterdemanding that the president retract the statement and apologize for “exposing him to entirely predictable possibility of physical harm.”
